S&S expands the boundaries of motorcycle performance with the latest High-Compression 136 and 132 Big-Bore Kits, which promise to elevate the ride with more torque, horsepower, and an exhilarating throttle response. With these kits, riders can experience the thrill of amplified power due to the increased compression these largest-ever bolt-on kits offer. Not only do they mesh flawlessly with standard crankcases without necessitating any machining, but they also retain your engine's original serial numbers. These kits smartly maintain the factory engine height, which facilitates hassle-free installation, and they come complete with the necessary gaskets. Additionally, the kits boast a factory-matching powder coat finish, ensuring that bikes retain a sleek, stealthy appearance. Ideal for those who demand peak performance from their machines, the 136 and 132 High-Compression Big-Bore Kits serve as your gateway to unrivaled power and a thrilling riding experience. Available in various finishes to complement your engine, these kits are recommended for those uncompromising riders striving for the pinnacle of performance.
To achieve the full 136" capacity, riders will need to use the S&S 4-5/8" Flywheel Assembly. It's important to note that these kits are compatible exclusively with H-D's 4-1/2 stroke (114" and 117") engines when considering stock stroke configurations, and they are not intended for use with HD's 4-5/8" flywheel.
